Bentall Operation in a Patient Wi̇th a Single Coronary Artery Anomalous

Abstract

Single coronary artery (SCA) anomaly is dened as the supply of the entire myocardium from single coronary ostium originating from a sinus of valsalva. SCA anomaly is very rare and is usually diagnosed incidentally during coronary angiography. It has been reported at a rate of 0.04% in diagnostic angiography series, and it has been reported to occur in 3% of all coronary anomalies (1). Although it is usually asymptomatic, there are rare cases with chest pain, arrhythmia, syncope, myocardial infarction and even sudden cardiac death (2). We present our patient with bicuspid aortic valve and SCA anomaly, who underwent modied bentall de bono operation for ascending aortic aneurysm and aortic valve regurgitation. In our patient, the left anterior descending (LAD) and left circumex artery (LCx) arise separately from a common trunk originating from the right sinus of valsalva. Due to this feature, we argue that there is no other bentall case dened in this group in the literature.
